Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

What to check on a viewing

On the Daihatsu Sirion, the steering items testers fail most are steering rack: gaiter missing or no longer prevents the ingress of dirt; steering track rod end: ball joint play.

The steering should feel tight with no clunks when you turn from lock to lock.
On a straight road the car should hold its line without constant correction.
Look for split rubber gaiters on the steering rack and track rod ends.

Ask for the car's MOT history: a steering advisory that repeats from year to year has not been fixed. GOV.UK MOT history.

More on the Daihatsu Sirion

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

The all cars figures cover all class 4 vehicles (cars and light vans) tested at the same age.
